How to partiton a memory card (P910i's memory stick pro duo) ?

[pacy4]

I use my P910i with a 4GB mem sitck SanDisk card, but it cause me troubles form time to time- some applicatons don't "like it" and some files can't be read. I'm wondering if symbian 7 os can work with multiple drives on one mem stick card and I’m looking for the software to partiton my card in four 1GB drives. Here what I found: see the attachment, but RPM don't recognise my drive as well as partiton magic Heard sth ab partition the stick under linux.
4GB is maximum theoretically allowed memory which can be addressed from 32 bit processor of P910i. If symbian 7 doesn't support multiple drives, maybe is possible to decrease the size of the 4GB card createing one small unused partiton of about 50mb to avoid the errors and leave the rest as the one big primary partition.
If somebody is familiar with this stuff, pls tell me more.

I manage the partition, but it seems that symbian 7 don't support partition cards. I will use it unpartitioned. The card works fine, if I don’t full the capacity more than 60%. Anyway it good that the p910i works with 4gb.
